DETAILED DESCRIPTION

[0021] This invention overcomes numerous disadvantages and problemsfound within the prior art. The prior art can be classified into complexand simple devices. While such complex devices are typically veryexpensive to manufacture and such simple devices are relativelyinexpensive to manufacture, there is a general lack of market acceptancefor any of those devices which indicates additional problems. None ofthose devices require a set of process conditions within which tooperate them. None require a projected cleaning space 13 within whichcleaning of the genitals and posterior parts of the body can take place.None of the devices can be economically installed into all types oftoilets, including flush tank and pressurized flush type toilets. Noneprovide a device that operates with a cleaning fluid composed ofmultiple ingredients other than water. None provide an environmentallyfriendly paperless toilet for use on boat toilets and other toiletsoperating in environmentally sensitive areas where sanitary systemcannot handle the processing of toilet paper. None define a sanitarycleaning process for the device itself, whereby commercially availabledisinfectant and deodorizer fluids 16 are an integral part of thecleaning process. The detailed description of the preferred embodimentswill address the aforementioned limitations and describe the solutionsprovided by the invention.

[0022] One preferred embodiment utilizes a conventional toilet flushtank 1 as the cleaning water source, thus avoiding any water pipingmodification all together. A submergible housing 2 is inserted into thetoilet flush tank 1. Said housing has sufficient volume to accommodateboth, the functional operating components and the cleaning fluid. Saidsubmergible housing 2 derives its cleaning fluid through a number ofcommunicating fluid entry openings 3 along its vertical axis. A residualcleaning fluid level is maintained at all times by having saidcommunicating fluid entry openings 3 start at a minimum volume level ofone (1) liter from its base. Said submergible housing 2 has a solid base4, can vary in geometric shape to accommodate various toilet models andcan be either open or closed at its top.

[0023] Said functional operating components located inside saidsubmergible housing 2 consist of the following: A cleaning fluid pump 5connected to a cleaning fluid pressure release valve 6, a means to pipe11 said cleaning fluid to an externally located cleaning nozzle 7, andan electrical heater 8 that heats said cleaning fluid to a temperatureranging from 25° C. to 50° C. Also residing inside said submergiblehousing 2 is an electrical power 21 and a control wire connection 9 tosaid cleaning fluid pump 5 to and said electrical heater 8. A pressuresensitive switch installed under the toilet seat is used to prevent pumpactivation without the weight of a person sitting on the toilet. Saidcleaning fluid pump 5 operates at a cleaning fluid pumping rate of 10 to50 milliliters per second.

[0024] The operating duration of said cleaning fluid pump 5 is a)controlled by the user by means of an on/off switch 10 or b) set withinthe apparatus. The fluid rate is set by means of a mechanical orelectrical controller within the said rate boundaries either set by theuser during the use or set as a constant within the pump itself. Thecleaning fluid temperature is set at the heater by controlling the rateof electrical power consumption or cleaning fluid temperature usingeither open loop or closed loop controllers.

[0025] A fluid pressure release valve 6, residing within the submergiblehousing 2, evacuates the cleaning fluid resident within the section fromcleaning fluid pump 5 to cleaning nozzle 7 while providing threeimportant functions. First, such valve interrupts the siphoning flow ofthe cleaning fluid after deactivating the cleaning fluid pump 5. Second,such valve provides a low level cleaning function for the contaminatedcleaning nozzle 7. Third, such valve prevents cold cleaning fluid frombeing present at the beginning of next cleaning cycle.

[0026] A means, which pipes 11 cleaning fluid from the cleaning fluidpump sto a cleaning nozzle 7 mounted within the confines of aconventional toilet bowl 12, accommodates the cleaning fluid flow ratesand cleaning fluid pressures and routes the cleaning fluid to the pointof use, the cleaning nozzle 7. Said means to pipe 11 cleaning fluid isparticularly configured for ease of installation and reliable operation.

[0027] Said cleaning nozzle 7 is mounted within the confines of aconventional toilet bowl 12 along its longitudinal axis at the back endof the toilet bowl 12 and below the rim of said toilet bowl 12. Saidcleaning nozzle 7 is positioned within a well defined area defined byhorizontal tolerance ranging from 0 to 150 millimeters below the rim ofsaid toilet bowl 12 and vertical tolerance bound by plus/minus 80millimeters from said longitudinal center line. Said cleaning nozzle 7is mounted within 0 to 50 millimeters of the inner wall at the back endbelow the rim of said toilet bowl 12. Said nozzle is positioned in anupward angle that is defined by a projected cleaning space 13 and boundby an area created by the inside rim of said toilet bowl 12.

[0028] Said cleaning nozzle 7 creates a single diffused stream 14 ofcleaning fluid directed toward said projected cleaning space 13 locatedwithin the confines of said toilet bowl 12; where, said projectedcleaning space 13 is parallel to the area projected by the inside cornerof the upper rim 15 of said toilet bowl 12, and said projected cleaningspace 13 is centered in the rear half 27 of the toilet bowl 12 along thelongitudinal center line 28 and segmented by the latitudinal center line29 of the toilet bowl 12. Said projected cleaning space 13 is singularin any geometric shape 30 fitting within the confines of an oval 31,centered in the rear half along the longitudinal axis of anyconventional toilet bowl 12, wherein said oval is bound in the rear endof the toilet bowl 12 by the toilet bowl 12 rim. The maximum width ofsaid boundary projected cleaning space 13 oval is 150 millimeters whileits maximum length is 200 millimeters.

[0029] Another variation of the said cleaning nozzle 7 is a specificcleaning cycle for the cleaning nozzle 7 itself. This cycle is achievedby piping and depositing a disinfectant and deodorizer 16 onto the outernozzle's surfaces 23 after every use to ensure sanitary conditions forthe subsequent user. This cleaning process is achieved through the useof a parallel piping conduit 22 that terminates at the upper end of thenozzle mount in a manner that assures complete coverage of the outernozzle's surfaces 23. The cleaning agent is located at the originatingend of said conduit. A control circuit 24 automatically dispenses saidcleaning agent after the nozzle is disengaged by the user. Readilycommercially available toilet cleaning agents, such as DOW disinfectantbathroom cleaner, can be used as a cleaning agent for this purpose. Thecombination of a self-cleaning nozzle 7 and a disinfectant anddeodorizer 16 will assure complete sanitary operation for every user.

[0030] Another embodiment of said cleaning nozzle 7 is one that createsa plurality of diffusing streams of cleaning fluid toward said projectedcleaning space 13 of the various preferred geometric shapes.

[0031] A key feature of this invention is the definition of a set ofprocess conditions for the various apparatuses. It is deemed veryimportant to have said cleaning fluid expelled by said cleaning nozzle 7at a specific flow rate and specific temperature. The preferred range ofsaid cleaning fluid flow is from 10 to 50 milliliters per second at atemperature range from 25° C. to 50° C. The specific set point of bothparameters are selected and set by the user according to personalpreference. The apparatus has the capability of controlling both theflow rate and the temperature within reasonable tolerance limits.

[0032] Said cleaning fluid can consist of water only, water mixed withsoap 17, water mixed with anti-bactericide 18, water mixed withanti-smelling agents 19 and any combination thereof. Those additives areadded via injectors 20 in liquid form or slowly released into thecleaning water in solid form, or any other known method of adding watersoluble components to said cleaning fluid.

[0033] The second preferred embodiment is one that uses an external coldwater supply 25 and an external housing 26 containing a pump 5, a heater8, an anti-siphon value 6, an electrical power source 21, a controlwiring 21, and sufficient free volume to hold cleaning fluid. Aside fromthe housing being external to a conventional toilet 12, this embodimentcontains all the functionality described in the above detail descriptionof the first embodiment of this invention. It is different from thefirst embodiment in that it does not require a said communicating fluidentry opening 3 within its housing, however, does require insulation 26around its body to minimize power use. The said external housing 26 canbe either foot mounted or wall mounted to fit the special requirementsof its users. The external housing 26 embodiment is particularly wellsuited for high frequency use installations; the cleaning fluid storagevolume and its internal components, such as the cleaning fluid pump 5and the cleaning fluid heater, can be sized to fit virtually all needsfrom extremely high usage at public facilities to low usage private usefacilities. The routing of cleaning fluid from the external housing 26to the toilet bowl 12, its installation, the location of its replaceablecleaning nozzle 7, and its use are identical to the description providedfor the first embodiment. This device can be installed into a boat in anenvironmentally friendly manner.

[0034] The third preferred embodiment is one that uses an external coldwater supply 25, pressure and flow regulator 32 and a pressurizedheating chamber 33 containing a heater 8, an electrical power source 21,a control wiring 9, and sufficient free volume to hold cleaning fluid.Aside from the housing being external to a conventional toilet 12, thisembodiment contains all the functionality described in the above detaildescription of the first embodiment of this invention. It is differentfrom the first embodiment in that it does not require a saidcommunicating fluid entry opening 3 within its housing, however, doesrequire insulation 26 around its body to minimize power use. The saidpressurized heating chamber 33 can be either foot mounted or wallmounted to fit the special requirements of its users. The pressurizedheating chamber 33 embodiment is particularly well suited for highfrequency use installations; the cleaning fluid storage volume and thecleaning fluid heater, can be sized to fit virtually all needs fromextremely high usage at public facilities to low usage private usefacilities. The routing of cleaning fluid from the pressurized heatingchamber 33 to the toilet bowl 12, its installation, the location of itsreplaceable cleaning nozzle 7, and its use, are identical to thedescription provided for the first embodiment with the exception of anflow control valve 34, a nozzle position control device 35, and a nozzlepush-in connector 36. This device can as well be installed into boats orother recreational vehicles in an environmentally friendly manner.
